Polyglutamic Acid Description
Polyglutamic Acid is a naturally occurring biopolymer primarily derived from the fermentation of Bacillus subtilis. It is composed of glutamic acid units linked by peptide bonds. PGA is known for its water-solubility, biocompatibility, and biodegradability, making it an attractive material in various fields

Polyglutamic Acid Applications
- Cosmetics and Skincare: PGA is used as a powerful moisturizing agent due to its ability to retain large amounts of water, even more than hyaluronic acid. It helps improve skin hydration, elasticity, and smoothness.
- Biomedical: In drug delivery, tissue engineering, and wound healing, PGA's biocompatibility and ability to form hydrogels make it useful for creating bio-friendly materials.
- Food Industry: PGA can be used as a food additive for texture modification and water retention, often found in fermented products like natto (a traditional Japanese food).
- Agriculture: It is sometimes used in soil conditioners to improve moisture retention in agricultural applications.

FAQs
Q1: How is Polyglutamic Acid produced?
PGA is typically produced through the fermentation of Bacillus subtilis, a process that results in a high molecular weight polymer of glutamic acid.
Q2: Is Polyglutamic Acid better than Hyaluronic Acid for hydration?
While both are excellent hydrators, Polyglutamic Acid has the ability to retain more water than Hyaluronic Acid. PGA also helps enhance the skin barrier and reduce the breakdown of Hyaluronic Acid, making it a complementary ingredient.
Q3: What forms of Polyglutamic Acid are available?
PGA is available in various molecular weights and formulations, depending on its intended use. For skincare, it's usually incorporated into serums, creams, or gels. In biomedical or food applications, it may appear in powder or hydrogel form.
Customized product forms are available upon request with a molecular weight range of 5 kDa to 2000 kDa. Available forms of PGA products include crystalline powder and hydrogel.
